Alex,

That's great information.

I saw no need for this process to be complicated and certainly would save alot of time compared to building a monoblock.

I always considered a monoblock to be the strongest way to attach barrels to an action. However a shoelump/demiblock is obviously strong enough as I've seen Heym (?) making a double .600 with this method......though a .600 is a relatively low pressure cartridge.

You're using 1205 degree silver solder. Is Hiforce 44 inadequate for this job ??? The assumption being a great fit between barrells and shoelump.

My interest in this is that if you use 1205 F solder/Hiforce 44 for the shoelump and Force 44 for the ribs/sights/forend hangar/front sling swivel mount then you should be able to hot blue the barrell assembly..............or is this blasphemy ????

What solder and flux do you use ???

The Holland dvd showed flame in direct contact with the barrells/shoelump. If I recall correctly.

By keeping the flame off the barrells/shoelump does this cut down on the incidence of scale ??

Great tip on the anti scaling solution.

Thanks very much for sharing your knowledge and experience on this. Thereby demistifying the process even further.
